From 310a997fd74de778b9a4848a64be9cda9f18764a Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Thu, 25 Apr 2019 13:06:18 -0400 Subject: [PATCH] ext4: actually request zeroing of inode table after grow It is never possible, that number of block groups decreases, since only online grow is supported. But after a growing occured, we have to zero inode tables for just created new block groups.
